The last members of the armed occupation of the Malheur National Wildlife Refuge began to give up their ground Wednesday after calls from supporters, Congress members and even their arrested leader to abandon the 26-day takeover.

After his arraignment in federal court, Ammon Bundy told the protesters through his attorney: "Stand down and go home."

Jason Patrick, a former roofer from Georgia who had stepped in to organize the 10 or so people at the federal bird sanctuary, left Wednesday, supporters confirmed. As did Duane Ehmer, the much-photographed horse-mounted cowboy from Irrigon, Oregon, sources said.

Wednesday's key developments:

* The ragtag remnants of the armed occupation of the Malheur National Wildlife Refuge started to give up their ground Wednesday after calls from supporters, Congress members and even their arrested leader to abandon the 26-day takeover.

* Mark McConnell said that Robert "LaVoy" Finicum was shot and killed after he charged law enforcement officers during a traffic stop Tuesday afternoon. McConnell claimed to be the driver of one of the occupiers' vehicles stopped by law enforcement officers.

Here are Wednesday's live updates:

7:40 p.m.: Amid a swirl of reports that armed militants might end their occupation of the Malheur National Wildlife Refuge after 26 days, Gov. Kate Brown remained wary late Wednesday about declaring victory too soon. "My understanding that there are occupiers at the refuge," she said in an interview with The Oregonian/OregonLive. "And obviously the Burns community is still feeling a lot of tension as a result."

5:36 p.m.: The ragtag remnants of the armed occupation of the Malheur National Wildlife Refuge started to give up their ground Wednesday after calls from supporters, Congress members and even their arrested leader to abandon the 26-day takeover.

5:09 p.m.: Les Zaitz is reporting that Jason Patrick, the leader of the refuge occupants for 24 hours, is surrendering, according to Stewart Rhodes of Oath Keepers. Duane Ehmer, the Hermiston cowboy who has paraded his horse around the refuge, also has left, according to sources. Only a handful of occupiers remain at the refuge, and patriot groups are hoping to convince them to give up. Occupation may soon be over.

4:45 p.m.: Add U.S. Sen. Ron Wyden's reaction to the events near Burns: "My overriding priority is that the remaining militants will leave the refuge peacefully and in short order. Oregonians expect their safety and the rule of law to be preserved, so I commend the FBI for moving to arrest the leaders of this illegal occupation. It is deeply unfortunate that these militants' actions have resulted in violence."

The message came moments after Bundy and six others were arraigned, one by one, on the ninth floor of courthouse on Southwest Third Avenue. The whole process took about 1.5 hours as more than 60 people wanted to witness the group's arraignment, but about 20 people couldn't fit. The full story is coming soon.

3:55 p.m.: Wednesday afternoon, Ammon Bundy and six other leaders of the group that has occupied the Malheur National Wildlife Refuge near Burns since Jan. 2 appeared in U.S. District Court in Portland, the U.S. Marshal's Service said.

They each face a charge of conspiracy to impede federal officers, a felony.

Ammon Bundy and six co-defendants will return to federal court for detention hearings on Friday at 1:30 p.m. They remain in jail in Portland for now.

The federal complains cites the extensive Facebook posts by Bundy and others about "tactical camping," alleged threats of following people home. For example, Jon Ritzheimer is accused to shouting, "You're BLM!" at a woman with a BLM shirt in the Safeway on Dec. 18, threatening to burn her house down.

From the complaint: On Jan. 2, a Harney County Sheriff's deputy told the BLM that occupiers had night-vision goggles, weapons and explosives at the refuge.

3:35 p.m.: B.J. Soper, a Redmond resident and member of the Pacific Patriots Network, said he and other community members have organized a vigil to honor Robert "LaVoy" Finicum tonight at the Silver Spur Hotel in Burns at 6 p.m.

Ammon Bundy and six others appeared one at a time before the judge. Bundy's appointed lawyer to issue a statement soon. Other defendants had court-appointed attorneys. The judge found each to be a serious flight risk; prosecution said it feared they might return to Malheur refuge for a last stand.

Bundy, through his lawyer, told the remaining occupiers to "Please stand down" and go home.

2:45 p.m.: A convoy of semi's just passed by (just before 3 pm) southbound onto Oregon 205 carrying more roadblock equipment and floodlights. The news has Twitter debating how long it will take before the cops bring a giant speakers to blast annoying music at the occupiers.

2:25 p.m.: By midafternoon at the roadblock on Oregon 205, a handful of reporters and satellite news trucks milled about, awaiting any action.

The closest thing they found came when four unmarked police vehicles left the barricaded area headed northbound, back toward Burns.

2:06 p.m.: Tim Smith -- a Burns-area businessman and member of the Harney County Committee on Safety, a group of six local residents formed at the urging of protest leader Ammon Bundy -- called the deadly confrontation outside of Burns "very unfortunate" and said federal authorities should disclose exactly what happened.

He said he knows the spot where the shooting occurred, an area 20 miles north of Burns in Devine Canyon along U.S. 395, and described it as a scene out of "an old western movie."

"This is pretty upsetting for everyone," Smith said.

But the committee still expects to take up Bundy's cause, he said. "We're going to continue to do what our goals have been," he said.

Bundy has said the occupiers of Malheur National Wildlife Refuge want two local ranchers freed from prison and local control of federal land in Harney County.

While endorsing the attention that Bundy brought to rural issues, Smith and the local committee members asked Bundy and his group of out-of-state protesters to leave the refuge and Smith repeated that Wednesday. A small group of people are believed to remain at the bird sanctuary about 30 miles southeast of Burns.

"For their sake, I hope they go home. ... We asked the Bundy group to go home a long time ago," Smith said.

1:30 p.m.: The courtroom is full, including the jury box, a U.S. Marshal said. About 20 still in the line won't make it inside.

1 p.m.: Greg Bretzing, the FBI Special Agent in Charge in Oregon, told Maxine Bernstein that the Deschutes County Major Crimes Team is investigating the officer-involved fatal shooting of Robert "LaVoy" Finicum.

At the federal courthouse, there are now more than 60 people in line for the arraignment of Ammon Bundy and six others.

Bretzing was joined by U.S. Attorney Bill Williams and Harney County Sheriff Dave Ward during the press conference, held on the 26th day of the standoff with occupiers. They expressed disappointment that a traffic stop on protesters had turned deadly Tuesday.

"It didn't have to happen," Ward said. "We all make chocies in life. Sometimes our choices go bad."

Bretzing said the FBI, state police and the Harney County Sheriff's Office had taken a "very deliberate and measured response" to the protesters who took hold of the refuge on Jan. 2. The occupiers there, he said, were given the opportunity to air their grievances. They had the chance to leave and return to their families, Bretzing said.

"Instead, these individuals have chosen to threaten and intimidate the America that they profess to love," he said.

"It has come to the attention of PPN that many individuals are responding to this news as a 'Call to Action'," the group, which includes Oathkeepers and III wrote in an issued statement. "During this time, cooler heads must prevail. We do not wish to inflame the current situation and will engage in open dialogue until all of the facts have been gathered."

The group ordered that no "mobilization" occur until they have had time to communicate with federal officials and complete a time line of what happened.

"In light of recent events PPN continues to support a peaceful resolution to the occupation of the refuge."

10:32 a.m.: B.J. Soper with the Pacific Patriot Network said that the FBI has cordoned off the wildlife refuge and that 10 occupiers remain inside. Soper of Redmond said that he is not at the refuge.

10:16 a.m.: The news conference will be at 11 a.m. Follow @Kelly_M_House, who will be live-tweeting from the news conference.

9:41 a.m.: The FBI in Portland has announced in a press release that the news conference will be pushed back to 11 a.m.; was scheduled in for 10:30 a.m. in Burns at the Harney County Chamber of Commerce.

9 a.m.: Ammon Bundy and the six others taken into custody on federal charges will be arraigned at 1:30 p.m. in U.S. District Court in Portland, according to the U.S. Marshal's Service. According to The Arizona Republic, Jon Ritzheimer, 32, will appear Wednesday afternoon in U.S. District Court for Arizona in Phoenix. Ritzheimer had been part of the armed occupation of the wildlife refuge, but he was visiting his family in Arizona and turned himself in to the Federal Bureau of Investigation Tuesday night.

In what purports to be a live stream on YouTube from the Malheur National Wildlife Refuge, men in camouflage and carrying weapons urge fellow militants to come to the refuge and fight. They talk about shooting at drones and appear to be operating a backhoe.

News conference: A news conference is scheduled for 10:30 a.m. Wednesday in Burns. U.S. Attorney Billy Williams, FBI Special Agent in Charge Greg Bretzing and Harney County Sheriff Dave Ward were to address reporters.

Roads still closed: This morning law enforcement authorities have stopped letting anyone past the barricade on Oregon 205, preventing anyone from accessing the wildlife refuge headquarters, including area ranchers.

Wes Land, a ranch hand in Burns, waited from his pickup on the roadside along Oregon 205 waiting for the chance to go to work.

Land's boss, Diamond Rancher Buck Taylor, runs cattle on land directly adjacent to the refuge. He was headed to that property to do his morning chores when officers manning a police blockade turned him away.

"I got to go out and feed cows," Land said from the drivers seat as he waited for word along with his border collie, Jack. "I just want to go down and do what I'm supposed to be doing, but they just keep telling me the roads closed."

The cows are usually fed by 7 a.m. When he is able to reach them, Land said he expects attitude from the 350 hungry animals.

Facebook video describes how Robert "LaVoy" Finicum died: A man claiming to be a driver during a Tuesday night roadside stop says in a Facebook video that Robert "LaVoy" Finicum, the spokesman of the Malheur refuge occupation, was shot and killed after he charged police during the altercation north of Burns.

Mark McConnell, in the video posted Wednesday morning, described the scene that led to Finicum's death and the subsequent arrest of eight people involved in the Jan. 2 takeover of the Malheur National Wildlife Refuge.

His account emerged as police established new checkpoints on roads leading to the refuge, where an unknown number of occupiers remained. Police said only local property owners would be allowed through. The number and exact location of the checkpoints couldn't immediately be established.

Yet the quiet man found his voice -- and a more confrontational calling -- in 2014 after joining Nevada rancher Cliven Bundy and dozens of others who stood up against a federal government they believed had overstepped its bounds.
